This topic is 3 years old, DMD can already generate 64-bit
programs on Windows (although I don't think DMD itself is 64-bit).

I still only see 32 bit version for Windows. I admit I have a 32 bit laptop , over 10 years old :) . All other laptops and pcs I have are 64 bit processors.
If anyone out there has a 64 bit; version 2.065 , for windows let me know.

You don't need a 64-bit version: Compiling 64-bit programs doesn't require a 64-bit compiler. Just install VC++, use the DMD 2.065 Win installer, and then toss in the -m64 flag when compiling. Works fine. Doesn't matter if DMD itself is 32-bit.

As Vladimir in IRC reminded me, there is one use-case: You may need it for some intensive CTFE stuff (excessive memory allocations and no freeing by the compiler). That is, if you need more than 3/4 gigs.

Right, there's certainly that. But that has nothing to do with whether you're trying to build a 64-bit or 32-bit program, and (at least for Windows) it isn't even an issue at all unless you actually are hitting that limit (unlikely for a newcomer to D). It sounded like steven kladitis was worried about just being able to create 64-bit programs. For that, it makes no difference if the compiler itself is a 32- or 64-bit build.

dmd -m64 ( windows ) says \bin\link not found :)

if the -m64 lets the compiled code use 64 bit registers and ints are now 64 bit then great! What is VC++, is it free?

Pointers are 64bits.
int is 32 bits, long is 64 bits.
size_t is 64 bits.

VC++ is Microsoft's compiler, DMD-x64 uses the de-facto standard
Microsoft linker, since OPTLINK doesn't support 64bit.
It is available for free.

long is 32 bits.
